Increasing evidence shows that activation of peroxisome proliferator-activated receptors (PPARs) plays an essential role in the regulation of vascular endothelial function through a range of mechanisms, including non-metabolic. Among these, the PPAR-mediated activation of endothelial nitric oxide synthase (eNOS) appears to be of considerable importance. The regulated and sustained bioavailability of nitric oxide (NO) in the endothelium is essential to avoid the development of cardiovascular diseases such as hypertension or atherosclerosis...

Kynurenine pathway (KP) is the primary path of tryptophan (Trp) catabolism in most mammalian cells. The KP generates several bioactive catabolites, such as kynurenine (Kyn), kynurenic acid (KA), 3-hydroxykynurenine (3-HK), xanthurenic acid (XA), and 3-hydroxyanthranilic acid (3-HAA). Increased catabolite concentrations in serum are associated with several cardiovascular diseases (CVD), including heart disease, atherosclerosis, and endothelial dysfunction, as well as their risk factors, including hypertension, diabetes, obesity, and aging...

AIMS: Platelets retain cytoplasmic messenger RNA and are capable of protein biosynthesis. Several diseases are known to impact the platelet transcriptome but the effect of non-valvular atrial fibrillation (NVAF) on platelet RNA transcript is essentially unknown. The aim of this study was to evaluate the impact of NVAF on platelet RNA transcript by measuring platelet genes expression in consecutive NVAF patients before and 3-4 months after pulmonary vein isolation (PVI) and compared to normal sinus rhythm controls (NSR)...

Endothelial damage has been implicated in the pathogenesis of vascular complications in β-thalassemia intermedia (β-TI). Soluble fms-like tyrosine kinase 1 (sFLT-1) is a member of the vascular endothelial growth factor receptor (VEGFR) family. Soluble fms-like tyrosine kinase 1 is an antiangiogenic protein that induces endothelial dysfunction by adhering to and inhibiting VEGF and placenta growth factor. The aim of this study was to assess the level of sFLT-1 in 35 children and adolescents with β-TI, correlating it with markers of hemolysis and iron overload as well as cardiopulmonary complications...

CD34+ circulating progenitor cells (CD34+CPCs) are a population of multipotent cells which can delay the development of atherosclerosis and cardiovascular disease (CVD) in conditions of increased CV risk. MicroRNAs (miRs) 221 and 222 modulate different genes regulating angiogenesis and inflammation; moreover, miR221/22 have beenshown to participate in differentiation and proliferation of CD34+CPCs, inhibiting cell migration and homing. miR221/222 in CD34+CPCs from hypertensive subjects are also increased and associated with CD34+cell number and reactive oxygen species (ROS)...

We read with great interest the article by Pascual et al., in which subclinical atherosclerosis in patients with hidradenitis suppurativa (HS) was assessed using carotid ultrasound. They found a higher prevalence of subclinical atherosclerosis in HS patients (30.7%) compared with controls (16.1%) and the association was significant in patients 40 years and older. Furthermore, traditional cardiovascular (CV) risk factors like hypertension (41.9%), diabetes mellitus (22.6%), and metabolic syndrome (38.7%) along with elevated systemic inflammatory markers including high-sensitivity C-reactive protein (Hs-CRP) (61...

Relative to those with European ancestry, African Americans have an excess incidence of nondiabetic chronic kidney disease predominantly due to two coding renal-risk variants in the apolipoprotein L1 gene (APOL1). This APOL1-kidney disease association is independent of systemic hypertension or blood pressure. Recent reports describe extra-renal effects of the APOL1 G1 and G2 renal-risk variants on cardiovascular disease (CVD), subclinical atherosclerosis, lipoprotein particle concentrations, and survival. However, results have been less consistent than those seen in kidney disease, and the observed APOL1 associations with CVD vary from risk to protective...

Strong experimental evidence confirms that HDL directly alleviates atherosclerosis. HDL particles display diverse atheroprotective functions in reverse cholesterol transport (RCT), antioxidant, anti-inflammatory, and antiapoptotic processes. In certain inflammatory disease states, however, HDL particles may become dysfunctional and proatherogenic. Flavonoids show the potential to improve HDL function through their well-documented effects on cellular antioxidant status and inflammation. The aim of this review is to summarize the basic science and clinical research examining the effects of dietary flavonoids on RCT and HDL function...

The VI European Guidelines for Cardiovascular Prevention recommend combining population and high-risk strategies with lifestyle changes as a cornerstone of prevention, and propose the SCORE function to quantify cardiovascular risk. The guidelines highlight disease specific interventions, and conditions as women, young people and ethnic minorities. Screening for subclinical atherosclerosis with noninvasive imaging techniques is not recommended. The guidelines distinguish four risk levels (very high, high, moderate and low) with therapeutic objectives for lipid control according to risk...

Diagnosis of dilation (D) cardiomyopathy (CMP) requires exclusion not only of inflammatory and genetically determined forms but also of some rare diseases. This 51 year old patient with history of moderate arterial hypertension approached a cardiologist because of new onset atrial fibrillation and dyspnea. Echocardiography detected dilation of all cardiac chambers with relatively preserved ejection fraction, causing suspicion of DCMP. Among conditions excluded were coronary atherosclerosis, congenital heart defect with left to right shunt, primary pulmonary hypertension, pulmonary embolism, hypertensive heart, tachycardia induced CMP, arrhythmogenic right ventricular dysplasia, noncompaction myocardium...

BACKGROUND: Cerebral white matter hyperintensities (WMH) on magnetic resonance imaging (MRI) are part of the spectrum of brain vascular injury accompanying aging and are associated with a substantial risk of stroke and dementia. We investigated the association of cerebral WMH burden on MRI with a DNA methylation-based biomarker of aging, termed DNA methylation age acceleration, which represents the deviation of the DNA methylation-predicted age from the chronologic age. RESULTS: In this cross-sectional observational study of 713 African-American participants of the Atherosclerosis Risk in Communities study, aged 51-73 years, estimates of predicted age were obtained based on two algorithms (Hannum et al...
